Background: We identified and analyzed the characteristics ofthe 100 most frequently cited articles published between 1965and 2007 in journals pertaining to urology and related fields.Methods: We selected 69 of the highest impact urology and subspecialtyjournals and 22 of the highest impact general medicaland medical research journals from the 2006 edition of JournalCitation Reports: Science edition. We identified the 100 mostfrequently cited urological articles published in these 91 journalsusing the Science Citation Index Expanded (1965–present).We reviewed and analyzed the articles.Results: The top 100 articles were cited a mean of 629 times(range 418–1435) and published between 1965 and 2003,with 89% published after 1979 and 54% published in the1990s. Fifteen journals were represented, led by The NewEngland Journal of Medicine (30), The Journal of Urology (22)and Lancet (11). Ninety publications originated from NorthAmerica (81) or the United Kingdom (9). Johns Hopkins University(13), Harvard University (5), Stanford University (5) andUniversity of California, Los Angeles (5) published the most articles.Five ur ol ogists were first authors of 2 or more of the articles.Fifty-six articles reported observational studies. Oncology(51) and transplantation (20) were the most commonly representedurological subfields.Conclusion: These top-cited articles in urology identify topics andauthors that contributed to major advances in urology. Observationalstudies and randomized controlled trials in oncology publishedin high-impact urological or medical journals constitutethe most common type of highly cited publications.Renseignements généraux : Nous avons dégagé et analysé les caractéristiquesdes 100 articles les plus souvent cités publiés dansdes périodiques spécialisés en urologie et dans les domaines connexesentre 1965 et 2007.Méthodologie : Soixante-neuf des périodiques les plus influents enurologie et dans les domaines connexes et 22 des périodiques lesplus influents en médecine générale et en recherche médicale ontété choisis à partir du Journal Citation Reports: Science Edition de2006. Les 100 articles les plus souvent cités dans le domaine del’urologie ayant paru dans ces 91 périodiques ont été dégagés àpartir du Science Citation Index Expanded (de 1965 à aujourd’hui).Les articles ont été passés en revue et analysés.Résultats : Les 100 principaux articles ont été cités en moyenne629 fois (écart : 418 à 1435) et publiés entre 1965 et 2003; 89 %ont été publiés après 1979 et 54 %, dans les années 90. Quinzepériodiques étaient représentés, avec en tête le New EnglandJournal of Medicine (30), le Journal of Urology (22) et Lancet (11).Quatre-vingt-dix périodiques étaient publiés en Amérique duNord (81) ou au Royaume-Uni (9). Johns Hopkins (13), Harvard (5),Stanford (5), et l’Université de la Californie à Los Angeles (5) sontles universités qui ont publié le plus d’articles. Cinq urologuesétaient les premiers auteurs de plus de 2 articles. Cinquante-sixarticles signalaient les résultats d’études observationnelles.L’oncologie (51) et les transplantations (20) étaient les sousdomainesles plus souvent représentés.Conclusion : Ces articles les plus cités en urologie permettent decerner les auteurs et les sujets qui se trouvent au coeur des principalespercées dans le domaine de l’urologie.

Bu makalede 1995 yılından beri Science Citation Index (SCI) ve Chemical Abstracts tarafından indekslenen Turkish Journal of Chemistry (TJC) bibliyometrik açıdan ele alınarak, bu dergide 1995-2007 yılları arasında yayınlanan 861 makale incelenmiştir. Araştırmada cevap aranan sorular şunlardır: TJC’de en verimli yazarlar kimlerdir ve yazarlar arasındaki ilişki durumu nedir? TJC’de çok yazarlılık durumu nedir? TJC’ye katkıda bulunan yazarların kurumları nelerdir? TJC’de yayınlanan makaleler Bradford, Lotka, Price Yasası ve 80/20 Kuralı’na uymakta mıdır? TJC’de yazarların atıf yaptıkları kaynak türleri nelerdir? En sık atıf yapılan dergiler hangileridir? Yapılan atıflar gözönüne alıdığında Kimya alanındaki çekirdek dergiler hangileridir? TJC’de yayınlanan makalelerin aldıkları ortalama atıf sayısı nedir ve atıflarda yıllara göre bir artış söz konusu mudur? Journal Citation Reports (JCR)’da ve SCI’de TJC’nin yeri nedir? Yazarlara ve kurumlara özgü tekil sonuçlar, makalede açıklanmıştır. Diğer taraftan yazarların durumu, Price ve Lotka Yasası ve 80/20 Kuralı’na uymamaktadır., Öte yandan, TJC’de yapılan atıfların Bradford Yasası’na ve 80/20 Kuralı’na uyduğu saptanmıştır. Yazarlar ağ analizi ile incelendiğinde ise, beş ve daha fazla makale ile katkıda bulunan yazarların iki ayrı etkileşimli grup oluşturduğu saptanmıştır. TJC’ye yapılan atıflar 1996 yılından beri istikrarlı bir atış göstermektedir.

Nicaragua is a small country in Central America and little has been published about its scientific output. Most of its publications available in international databases are about medicine and are produced by Universidad Nacional Autónoma de Nicaragua (Managua) as part of international collaborative teams. In this article we analyzed in more depth, and for a longer period than any previous study, the presence of Nicaraguan publications in the Science Citation Index Expanded until January, 2016. In total, 837 Nicaraguan articles were published in 456 journals (the top journal is the American Journal of Tropical Medicine and Hygiene). Internationally collaborative articles with 94 countries accounted for 92 % of articles, while only 8.5 % were exclusively Nicaraguan. The most cited article described the use of ketoconazole to treat Leishmaniasis. The authors with more publications in the database were A. Balmaseda, R. Peña, W. Strauch, and F. Bucardo. The top cited, exclusively Nicaraguan articles dealt with health problems, forest tenure, and food production. The article citation lifespan is surprisingly long: over 70 years. Most citations start seven years after publication and are not recorded by the Science Citation Index, which for that reason cannot be considered valid to evaluate the impact of Nicaraguan research. The predominance of English publications may reflect a bias of the database itself. Probably most of the scientific production of Nicaraguan scientists is published in Spanish, in many regional journals not included in the SCI-EXPANDED. Nicaraguan research centers lack appropriate infrastructure, staffing and financial resources: future achievements for Nicaraguan science should include a fair presence of female researchers, peer-to-peer level participation in international teams, and less dominance of health technologies.
